didn't see "md5 mismatch" error on today's Rawhide noarch packages

There was at least one noarch package in today's Rawhide updates, and I
didn't see the usual "md5 mismatch" error when rebuilding the RPMs.
Does this mean that they are now being built on a little endian arch
(probably Intel), and if so, will this be done consistently from now on?
(At least until xz is changed to generate the same compressed output on
big endian.)
